如何让python在我的代码中识别正确的值？字典

Question

for i in range(n): 
    while len(dictionary)>0:
        choice = random.choice(list(dictionary.keys()))
        correctAnswer = dictionary[choice]
        print("English: ",choice)
        guess = input("Spanish: ")
        dictionary.pop(choice)
        if guess == correctAnswer:
            print("\nCorrect!\n")
        else:
            print("Incorrect\n")
            wrongAnswers.append(choice)
        break
print("\nYou missed", len(wrongAnswers), "words\n")

嗨，我正在尝试在python上创建一个词汇测试。我的代码一直运行到这个块。程序提示用户猜测后，程序会说它是不正确的，即使它是正确的答案。这段代码中有错误吗？我怎么能绕过这个？

这就是它的样子：
英语：白
西班牙语：blanco
不正确

英语：purple
西班牙语：morado
不正确

谢谢！

完整代码：

def main():

wrongAnswers = [] 

print("Hello, Welcome to the Spanish-English vocabulary test.") 
print(" ")
print("\nAfter the test, this program will create a file of the incorrect answers for you to view")

print("\nTo start, please select from the following options: \nverbs.txt \nadjectives.txt \ncolors.txt \nschool.txt \nplaces.txt") #sk

while True: #SK
    selection = input("Insert your selection: ").lower() #user inputs selection #sk
    if selection == "verbs.txt" or selection == "adjectives.txt" or selection == 'colors.txt' or selection == 'school.txt' or selection == 'places.txt':
        print("You have chosen", selection, "to be tested on.")
        break
    if False:
        print("try again.")
